    Development of Technical Pan Film.

    For low contrast Kodak recommends Technidol; Photographers' Formulary
    recommends their TD-3. Does anyone have experience with both of these

    I've used Technidol quite a bit. I can recommend it to you and have even
    seen some of the more experienced and known names on these forums state 'The
    best way to process TechPan is with Technidol'.

    Regardless, the best tips I can offer to you for TechPan in Technidol is
    to follow Kodak's instructions to the letter. Use a water bath and shake
    the tank like you were making a martini for Mr. James Bond;~). The image
    graduation is smooth, contrast is controlled and reasonable - with my
    experience showing a Grade 2 to 2.5 on average from wide latitude pictorial

    Time/temp from my notes has shown 68F and 8min 30 sec - exactly - to work
    well. What I mean by that is you need to be pouring in the stop bath at
    00:8:30. I also add 3 drops of Photo-Flo 200 to the developer. I tank
    process and have not tried rotary on the Jobo. I add the Photo-Flo to
    reduce surface tension. With all the air introduced during the shaking, it
    can only help. Foaming has not been a problem.

    I have really begun to like this combination. But then again, I loved
    the old Pan-X in Microdol or Rodinal. I guess it's safe to say - for
    pictorial work - I'm a member of the invisible grain crowd. I rate it at
    ISO 25 and average the scene with a spot meter. I get wonderful 16X20
    enlargements from 2 1/4 negatives.

    Sorry, I can't offer any advice on the PF TD-3. Some have also used
    Rodinal at very high (1:100) dilutions. I have even heard and seen the
    results from someone using T-Max developer and rating TechPan at ISO 200 -
    400 (see below, the link still works). Someday, I'm going to have to try

    Try this also:
    30 minutes in Rodinal 1:300 added with a sodium sulphite teaspoon per
    liter of solution for an exposure index of 25 ISO.
    Agitate for the first minute and then for 30 seconds only at the 12nd
    and 25th minute,leaving the tank "immobile" for the rest of the time.
    Very impressive results!I usually use this for developing Tpan.

    TD-3 is great though I used EI 16 when I was testing it out. Very, very
    sharp and very fine grain with the best tonal separation I've found for Tech
    Pan. The images (negatives) had a very unique look as well. If I were playing
    with Tech pan today TD-3 would be my developer of choice. Alternatives would be

    Delagi #8 (EI 32)
    Water @ 100F500 ml Sod.Sulfite25 g
    Phenidone1.4 g
    Borax1 g
    Benzotriazole (0.2%)15 ml
    Water to make 1.0 L

    Used full strength at 68F for 15 min

    P.O.T.A (EI 32)
    Water 750.0ml
    Sod.Sulfite 30.0g
    Phenidone 1.5g
    Water to make 1.0 L

    Rodinal (EI 25)
    1:100 for 7 minutes at 70F
